Application filed January 3, 1921.

ToaZZ 'whom t may conce/m.'

Be it known that I, EDMUND H. LUNKEN, citizen of the United States, and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and'useful Improvements in W'indows, of which the following is a full, clear, and exact description, reference being had to the drawings `forming part vof this .specication `My i-nvention relates to windows, and more particularly that type of window known as a pocket window, wherein the sashes are free to pass into a wall pocket, thereby removing them partially or entirely from the window opening.

r-lhe problem of producing a window with a metal weather stri-p which will not only be permanent, but also vhave suthcient ad justable or automatic taire-np to prevent rattling and still will always be free 4for passage ofthe sashes into the window pocket and also will leave the sashes tree to pass eachother in both directions is a difficult One.

A take-up in -the weathering between the two sashes will act to spread them apart at the meeting rails, a 4shitting of the weather strips bodily will tend to throw out of true line the path into .the windo-w pocket and spring strips particularly where run lengthwise of the window lopenings require excessive original expense, as well as great time and care in installation.

Among other things it is my object to provide an inside metallic strip for windows, which may be mounted in the window frame, and the sashes fitted thereto prior to the installation of the wooden head strip ordinarily employed to trim the inside ot the window frame. This bead it is my object to form so that it may be bent to take up looseness and will retain this bent formation.

lt is my object to provide an improved method of mounting the parting bead between the upper and lower sashes-o the window, so as to save expense, in comparison with the usual methods of installing metallic beading.

These features, taken together with other metal weather stripping improvements, which form no part in this invention aside from their combination with the novel de- Serial No. 434,586.

v ices indicated, will provide a fully weather tight window, with a take-up feature of great simplicity.

l. accomplish these objects by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed, whereby as noted, a permanent weather stripping for windows is provided, same being Vespecially adaptable to pocket windows.

In the drawings,

Figure l is a longitudinal vertical section of the window in the form of a pocket window.

Figure 2 is a perspective detail illustrating a method of attaching the central or parting bead strip.

Figure 3 is a perspective detail illustrating the inside bead or strip.

Figure l is a detail section of the weather stripping for meeting rails of the sash.

Figure 5 is a perspective view oi4 one Aof the upper inside corners of the window.

As shown the window frame l is formed with a wall pocket 2 therein, the frame with pocket walls mounted thereon being usually constructed in my preferred design as a unit, fully erected and fitted with sashes at the factory.

The sash weights are set into the window over pulleys 3, mounted on long arms 4, whereby they may be provided `with a point of attachment adjacent the frame opening, and may be removed ror rie-.placing weight cords, and the like, while locating the pulley at the upper end of the pocket.

The lower sash of the window is shown as having bottom rail 5, a top rail 6, and side rails 7. The upper sash has a top rail 8 and a bottom rail 9 andside rails l0.

In setting the sash into the frame, there is a parting strip Vprovided which is made up of a metal channel strip 1l, with a `filler 12 of wood. The edges of the strip l1 may be bent down as at lla to hold the ller in place. There are two of these parting strips, one on each side of the window set within a groove in the Jtrame. Part of my invention consists in the novel method of mounting such a strip, the specific details of the strip being non-essential.

lt will be understood that the ordinary way of mounting a strip of such a character would be to form at the sides of the channel strip or suitably weld or rivet to the strip, some form of ears, which would be countersunk into the body of the frame, and screwed down. This is quite expensive, and adds considerably to the cost of the window, as vlell as giving rise to defects in workmans 1p.

In order to avoid this I drill slanting holes in the metal strip and employ headless screws 12a which are screwed down into the wooden frame through the channel pieces, with their heads lying within the confines of the channel walls. 'Ihe channels will thus be removable, and still very inexpensively mounted in place.

The inside beading for the sashes will preferably consist of a metal strip having a base 13, which is screwed down along the frame in a vertical position, and a return bent wall 14, which extends inwardly of the frame, and against which the sash side rails will bear.

The usual inside wooden beading strips 14a may be mounted directly over these metal pieces so as to obscure them from view, and provide a window of the usual outward appearance. The duplication of this structure on the outside of the window will not be done, where screens are Vto be used.

When made up in a factory itis evident that the sashes may be fitted very closely to the metal walls 14 of the strips, and for the screens a channel piece similar to the metal parting strip will be used against which the outside sash will be closely tted.

It will be noted that the beading leleL along the sides may be duplicated at 14d along the top of the win-dow frame, and that the carpenter will not be disturbed with the problem of providing clearance for the lower sash rails at the mouth of the pocket. Thus the strips 14 which may be extended beyond the end of the side trim strips la keep the sash rails spaced away from the beading a sufficient distance to enable them to clear the inner pocket wall. The carpenter Vmerely matches the inside edges of the top trim with the like edges of the side trim and need notl watch his clearance.

Between the rails of the two sashes there will be provided a spring strip, which will permit of the rails passing each other. Thus on the upper rail of the lower sash I mount a strip comprising an outer piece 15 and an inner piece 16, which will spread under tension to provide a resilient contact ineinber.

It is, as noted, a fairly easy matter in a factory devoted to the construction of windows to lit the sashes so that they run snugly but smoothly between the frame beads, and so that wiping contact will be maintained between the sashes when the window is lances closed, as well as a wiping contact of the upper rail of the upper sash with the pocket mouth. l

After a period of use, particularly in dry weather', there is likely to be a shrinkage in wooden sashes, such that they will rattle in the guideways, and will not be weathertight. When this occurs in the construction now described, any mechaniecan run a screw driver or any desired edge tool along the space between the wall la and the inside wooden bead or trim la, and bend the double wall 14; of the metal beading strip inwardly toward the sash. The stripy will be of metal which will bend and retain the bent shape so that a slight bending and shaping of the strip to take up shrinkage will serve to prevent all rattle and make the sashes again weather tight. Spreading of the central bead would not be satisfactory in many cases since this would so part the sashesV at their meeting rails that it would destroy a wiping contact at this point. Spreading of the screen channel, similar to the parting bead channel will be resorted to, 'to take up play in the outer or upper sash. Y

Should the sashes swell again, thebent metal would Vbe forced back against the wooden bead and probably flatten somewhat the double wall of the bead strip, thereby maintaining the proper fit and weather tightness at all times subject to the bending above referred to when looseness occurs.

Having thus described my invention,what I claim as new and desire to secure by Letters Patent, is :--V

1. In a window, a parting bead betweenV the sashes thereof, comprising a channel strip of metal, set into the windowframe, and projecting therefrom and screws inserted at a slant through bored holes in the walls of said channel strip into theV frame for retaining the strip removably in place.

2. In a window, a parting bead between the sashes thereof, comprising a'strip of metal having a rectangular conformation eX- tending inwardly from a win-dow frame and having holes bored Vslantwise through the walls thereof, and headless screws set into said holes from the outside of the strip and screwed into the window frame, for the purpose described.

3. In a window, 'a parting bead between the sashes thereof, comprising a stripof metal having a rectangular conformation and having holes bored slantwise through the walls thereof, and headless screws set into said holes from the outside of the strip and screwed into the window frame, for the purpose described, said screws being headless so that they may be inserted with their heads within the confines of the walls of said strip.

4. In a pocket window, the combination of a frame, and a. pocket at one end thereof, a sash in said frame, trim strips on the inside of the frame, extending along the sides of the frame and the base of the pocket, and a metallic Weather strip set along the outer edge of each of the trim strips at the sides of the frame in Contact with said Strips and extending into said pocket, whereby the trim strips at the base of the pocket may be readily matched with the side trim strips by being placed against said Weatherstrips, and the metal Weather strip will keep the sash away from the pocket base and prevent rubbing therewith, upon moving the sash into the pocket.
